无法在我的笔记本电脑上连接到 AWS RDS（尽管我的 laravel 应用程序通过弹性 beantalk 托管可以与 RDS 交互）

Question

I created an AWS Elastic Beanstalk env and deployed my laravel app. My laravel app can connect to the database but i cannot connect to the database using any database client on my laptop.

I have already added my IP address under EC2 -> Security Groups -> Inbound rules (followed an advice from another stackoverflow post) Inbound rule entry

My RDS access is Publicly accessible under RDS -> Databases -> Connectivity & Security

I keep getting this mysql client error

What am I missing here? Do I need to change anything else for accessing the RDS remotely.

Thanks!

Answer 1

Is this RDS instance in a private or a public su.net? If it's in a private su.net, it'll not be reachable from outside the VPC. You'll have to create a jump server to connect to it.

You can go through a few checks if RDS is already in the public su.net.

1. make sure SG attached to RDS has an ingress rule on the Mysql port for your IP address.
2. if your IP address is dynamic, make sure it hasn't changed after adding the ingress rule to SG.
3. make sure that the public su.net's route table has a route to the inte.net gateway as well.
4. check instance reachability by running the command te.net <RDS_hostname> <Port> on the terminal.
